Me pēhea te whiriwhiri i te arotahi kāmera ahumahi tika

Hei wāhanga matua o te pūnaha tirohanga mīhini, ka tāutahia ngā kāmera ahumahi ki te raina huihuinga mīhini hei whakakapi i te kanohi tangata mō te ine me te whakatau. Nō reira, ko te whiriwhiri i tētahi karāhe kāmera e tika ana he wāhanga nui hoki o te hoahoa pūnaha tirohanga mīhini.

Nā, me pēhea tātou e whiriwhiri ai i tētahi mea e tika anaarotahi kāmera ahumahiHe aha ngā take hei whakaaroaro māu i te wā e whiriwhiri ana i tētahi arotahi kāmera ahumahi? Me titiro tahi tātou.

1.Ngā whakaaro taketake mō te whiriwhiri i ngā arotahi kāmera ahumahi

①Kōwhiria te kāmera CCD, CMOS rānei kia rite ki ngā tono rerekē

Ko ngā arotahi kāmera ahumahi CCD te nuinga o te wā e whakamahia ana mō te tango whakaahua o ngā mea nekeneke. Ko te tikanga, me te whanaketanga o te hangarau CMOS, ka whakamahia hoki ngā kāmera ahumahi CMOS i roto i te maha o ngā mīhini whakanoho maramara. He whānui te whakamahinga o ngā kāmera ahumahi CCD i roto i te mara o te tirotiro aunoa tirohanga. He whānui te whakamahinga o ngā kāmera ahumahi CMOS nā te iti o te utu me te iti o te whakamahinga hiko.

Ka whakamahia ngā kāmera ahumahi i roto i ngā raina whakaputa

②Te taumira o ngā arotahi kāmera ahumahi

Tuatahi, ka whiriwhiria te taumira mā te whakaaro ki te tika o te mea e tirohia ana, e inehia ana rānei. Mena ko te tika o te pika kāmera = te rahi o te tirohanga ahunga-kotahi / te taumira ahunga-kotahi o te kāmera, ko te taumira ahunga-kotahi o te kāmera = te rahi o te tirohanga ahunga-kotahi / te tika ariā.

Mena ko te whānuitanga tirohanga kotahi he 5mm, ā, ko te tika o te ariā he 0.02mm, ko te taumira ahunga-kotahi he 5/0.02=250. Heoi, hei whakanui ake i te pumau o te pūnaha, kāore e taea te whakataurite i te uara tika o te ine/mātakitaki me te whakamahi i te kotahi wae pika anake. I te nuinga o te wā, neke atu i te 4 ka taea te whiriwhiri, nō reira me whai taumira ahunga-kotahi te kāmera o te 1000 me te 1.3 miriona pika.

Tuarua, i runga i te whakaaro ki te putanga o ngā kāmera ahumahi, he pai te taumira teitei mō te tirotiro i te tū, te tātari me te mōhio ki te pūmanawa mīhini. Mena he putanga VGA, USB rānei, me tirotiro i runga i te mata tirotiro, nō reira me whai whakaaro anō hoki ki te taumira o te mata tirotiro. Ahakoa te teitei o te taumira o te hangarau tirohanga ahumahi mengā arotahi kāmera ahumahi, kāore e tino mārama mēnā kāore i te rawaka te taumira o te aroturuki. He āwhina anō hoki te taumira teitei o ngā kāmera ahumahi mēnā kei te whakamahi kāri mahara, kei te tango pikitia rānei.

③Anga kāmerautuo te arotahi kāmera ahumahi

Ina neke te mea e inehia ana, me whiriwhiri he karāhe kāmera ahumahi he tere anga teitei ake. Engari i te nuinga o te wā, ko te teitei ake o te taumira, ko te iti ake o te tere anga.

④Te whakataurite i ngā karaihe ā-ahumahi

Me iti ake, me ōrite rānei te rahi o te maramara pūoko ki te rahi o te arotahi, ā, me ōrite hoki te maunga C, CS rānei.

2.Ētahi atucngā whakaaro mōcte whakarite i termāramacāmeralngā

①C-te whakairi, te whakairi-CS rānei

Ko te tawhiti atanga o te C-mount he 17.5mm, ā, ko te tawhiti atanga o te CS-mount he 12.5mm. Ka taea anake te arotahi ina tīpakohia e koe te atanga tika.

Ngā rerekētanga i waenga i ngā atanga rerekē

②Rahi o te taputapu whakaahua-ātete

Mō tētahi maramara whakaahua-ā-ringa 2/3-inihi, me whiriwhiri e koe tētahiarotahi kāmera ahumahie hangai ana ki te koiri whakaahua. Ki te whiriwhiria e koe te 1/3, te 1/2 inihi rānei, ka puta he kokonga pouri nui ake.

③Tīpakohia te roa o te arotahi

Arā, whiriwhiria he karu tirohanga ahumahi he nui ake te whānuitanga o te tirohanga i te awhe tirohanga.

④Me ōrite te hohonutanga o te mara me te taiao rama

I ngā wāhi he nui te māramatanga, he nui rānei te kaha o te māramatanga, ka taea e koe te whiriwhiri i tētahi kōhao iti hei whakanui ake i te hōhonutanga o te mara, ā, hei whakapai ake i te māramatanga o te pupuhi; i ngā wāhi kāore i te nui te māramatanga, ka taea e koe te whiriwhiri i tētahi kōhao nui ake, ka taea rānei e koe te whiriwhiri i tētahi maramara whakaahua-tairongo he tino tairongo.

Hei tāpiritanga, kia pai ai te whiriwhiri i te arotahi kāmera ahumahi tika, me aro atu hoki koe ki ētahi au rongonui. Hei tauira, kua tino ahu whakamua ngā pūoko whakaahua i ngā tau tata nei, me te au ki te piki haere o ngā pika hei whakapai ake i te taumira ongā arotahi kāmera ahumahi, me te tairongo teitei ake (ngā pūoko whakaahua whakamārama-muri). Hei tāpiri, kua pai ake te hangarau CCD, ā, inaianei kua nui ake ngā mahi e tohaina ana me ngā pūoko hangarau CMOS.

Ngā Whakaaro Whakamutunga：

Kua oti i a ChuangAn te hoahoa me te hanga tuatahi i ngā karāhe kāmera ahumahi, e whakamahia ana i roto i ngā āhuatanga katoa o ngā tono ahumahi. Mena kei te hiahia koe, kei te hiahia rānei koe ki ngā karāhe kāmera ahumahi, tēnā whakapā mai ki a mātou i te wā e taea ai.
